apparent!}^ very broadl}' and feebly bisinuate. The head in the 

 female is relatively but little smaller, but the prothorax is some- 

 what more narrowed toward apex and the elj'tra just perceptibly 

 and gradually wider behind. The ungual appendages are ver}- 

 short and rudimentarj^, and the anterior tibiae completeh' devoid 

 of spinules. I have before me a large series agreeing in ever}- 

 respect witli the original type of LeConte. 



10. D. depressiiliis n. sp. — Ovoidal, feebly convex, shining, black; legs 

 rufo-ferruginons, the hind thighs, except at tip, black, the anterior and inter- 

 mediate piceous-black ; antennae black throughont; laln'um, mandibles and 

 apex of the epistoma pale piceo-rnfous; pubescence cinereons, rather short, 

 moderately dense, intermingled with a few erect black setse anteriorly and with 

 more numerous, very short and scarcely distinct erect pale hairs on the elytra. 

 Head rather small, three-tifths as Avide as the prothorax, strongly and closely 

 punctate and slightly rugose, the impressions nearly obsolete; labrum feebly 

 arcuate at apex; eyes moderately small, convex; antennte long, filiform, the 

 joints rounded. Prothorax twice as Avide as long, the sides parallel, distinctly 

 and almost evenly arcuate, the edges feebly and finely crenulate; basal angles 

 obtuse but not rounded, the apical feebly obtuse and not very blunt; apex 

 and base subequal, feebly and almost equally arcuate; disk finely and some- 

 what closely punctate, rugose in a wide and feebly delimited lateral area. 

 Elytra one-half longer than wide, quite distinctly wider at apical two-fifths 

 than at base and about two- fifths wider than the prothorax; apex almost semi- 

 circular; disk finely, evenly and rather closely punctured. Under sirrface 

 finely and somewhat sparsely luteo-pubescent. Length 2.6 mm. ; width 1.25 

 mm.

A moderatel}^ large species, readily recognizable by the sub- 

 depressed form, small head, very transverse prothorax and colora- 

 tion of the legs. It is represented in my cabinet by a single 

 female t3'pe.

Suboval, rather narrow and convex, the head and pronotum

 piceous-black, the legs rufo-ferruginous; antennoe blackish-pice-

 coarse and dense, closely decumbent, fulvo-cinereous in color and 

 without trace of intermixed erect hairs. Head three-fourths as
